TRIGGER MECHANISM FOR- FIREARMS.

' SPECIFICATION forming part of Letters Patent N 719,019, dated January 2 7, 1 503. Application iiled June 28, 1900- Serial No. 21,876 (No model.

to impart an unintended motion to the rifle,

also that the pulling of the trigger of military rifles by meansof the forefinger is inconvenient and firing uncertain when the soldier is lying on the stomach. I This invention relates to a trigger which is i not situated'below, as usual, but on the neck of the rifle butt or stock, either on the top or 20. sidewise, and arranged in such a manner that the chargemay befired by means of the thumb of the right or left'hand. The function of the -,-ordinary"'-;igger is performed by a slide acting on tliietrigger-lever and guided in such a manner that it may be caused to slide on the stock by a suitable motion of the thumb.-

The construction is represented by the drawings, of whichv Figure 1 is a longitudinal section through aportion of a rifie embodying my invention.- Fig. 2 is a cross-section of the same along line "A B of Fig. 1, and Fig. 3 a plan.

Instead of an ordinary trigger I employ a plate orblock 1), adapted to slide on the neck of the stock. The block or slide p'is adapted to be engaged by the thumb and is movable toward or away from the shoulder in a line parallel to the longitudinal axis of the gun. It has'a downward projection a, guided in a slot of the rifle-stock and connected by a pivotal jointwith a rod.s,*which carries at its front end a friction-roller 'r. The latter rests "on a curved arm of the trigger-lever it, provided with the searnose c, which is integrally 5 formed therewith. By drawing the plate 19.

abutment or rest for the roller 7' (that can be felt during the shifting of the plate 19) before a the final down motion of the lever '71. and before the firing takes place, so that only a slight further motion is required for releasing the sear. In the case of double-barreled rifles two plates 10 are placed side by side. In order to afford protection for the plates, they are arranged in a recess of the stock, or the latter-is provided with an upward projection e on the right and left of the plates. (The trigger mechanism describedabove has the advantage that it can be operated more conveniently and smoothly than those requiring the use of the forefinger, that its opera- .tion by the thumb is not liable to afiect the other parts of the hand holding the rifle, and that consequently there is less danger of shifting the rifle by pulling the trigger. As the rifle is completely closed at the bottom and the plate 10 closes tightly the opening in the, stock provided for the motion of the projec tion a, the interior of the rifle is better protected against moisture than that of ordinary What I claim is- A gun provided with a slide movable on the grip of the stock parallel to the longitudinal axis of the gun, a rod connected to the slide, a roller carried by the rod, and a trigger-lever havinga sear-nose, a notch and a curved arm, said notch and arm being adapted to'be engaged by the roller, substantiallyas speci- Signed byzme at Dusseldorf, Germany, this 16th day of June, A.
